According to a friend of mine, who works for a Ford dealership, that deal of blowing plugs was pretty much in the late '90's 5.4 engine. He's a parts manager, and although it happened, it wasn't as bad as what you might have read on the internet. I have a 2004 Ford van with 83,000 miles on it, and getting between 18 to 20 MPG with it. The engine is the 4.6, and the only complaint I have so far, is it needs a plug replacement, and the dealer I bought it from, and the one my friend works at, both quoted me $300+. Just because it's a van,(E-150), and it takes a special tool from Ford to change plugs.(I looked under the hood and the doghouse, and I can't even see the center 2 plugs on either side.) So I guess I'll bite the bullet and get it done, with the knowledge that it only has to be done every 75,000 to 80,000 miles. gypsyman
